Rhombus
Rhombus formulas and properties
A rhombus is a flat quadrangule with four sides of equal length. Opposite sides are parallel and opposite angles are equal. Alternatively, the rhombus can also be defined as a parallelogram whose diagonals intersect each other at right angles.
Properties
- Opposite sides are parallel.
- Opposite interior angles are the same size, adjacent interior angles are supplementary, their sum is 180°.
- The interior angles are bisected by a diagonal.
- The two diagonals are perpendicular to each other and bisect each other.
- It has an incircle and is therefore a tangent quadrilateral. The center of the circle is the intersection of the diagonals.
